Golf Tee Mod...

E92Adam · 07-10-2007, 02:26 PM

I have read a bunch about everyone and the sound/performance of the golf tee mod. The sound is different, much different.

Performance wise, I'm not to sure what you gain, but I do know that when i did the mod, sitting still the car seemed to respond and jump in RPM quicker when revving the engine.

I am posting 2 WAV files first stock and then one modded. I did not move the mic nor the car. The mic was placed about 5 feet off the passenger door.
The two sounds clips were taken approximately 5 mins apart. I did not do the golf tee thing. For comparisons sake I used one of these.. and pinched the hose off.

Yeah i saw your vid.. scared me with the back up thing... thought your camera was a goner.

bartman32 · 07-10-2007, 06:11 PM

So how easy to do this? Is there any downside?

E92Adam · 07-10-2007, 07:40 PM

I don't know about new... and it's an old topic but i haven't seen anyone post a comparison of the two. Thought it would be helpful for those considering it.

I love hearing the turbos spooling!

Alpine · 07-10-2007, 11:29 PM

Wait.. I thought people already decided it was bad for the e90? Is it good for the turbo though?

pittyinSC · 07-22-2007, 03:21 PM

Is it bad for an e90 330?

rloyola0426 · 07-25-2007, 03:45 AM

Unlike NA cars, the best exhaust for a turbo engine is NO exhaust. No backpressure results in the largest amount of power as well as the fastest spool up. With that said, having a flap closed in one of the exhaust tips will do nothing but make the car quieter and create more backpressure, which isn't needed. On a NA 3'er one could argue that you need that backpressure for low end torque, but that can also be doubted since much less restrictive aftermarket exhausts have shown to even have gains down low. In any case, its definitely not helpful for the 335, unless you would like a more quiet exhaust.

Au335... did you take that clip when the engine was up to temp or was that from a cold start? I'm just asking because all I have read on here was about how it sounded better during cold starts, but nothing much about how it sounded once the car was warmed up.

Much Appreciated... Too many Long timers with nothing to do but bitch... Forgetting that there are PLENTY of folks out there who haven't heard about this and aren't used to messing with their cars....

I appreciate the links.. I just used a couple of zips ties about a week ago to see what I thought...

So far I am like

I like the sound when messing around, but when just going down the road the extra noise gets old after awhile.

AndreTheGeek · 07-26-2007, 12:20 PM

I just tried this mod, and I don't like it. It is subtle, but I think cheaper-sounding.

I think BMW engineered this correctly, and having twice the gases going through one pipe at certain RPMs gives a more refined sound.

LEDZEP · 07-26-2007, 12:22 PM

I'm planning on doing the football tee mod to my car.

So there.
